It is one of my favorites, too. It was taken on the "17 Mile Drive" outside Monterey, CA and Carmel, CA (near the Pebble Beach Golf Course). The tree on the right is the iconic "Lone Cypress" which is the emblem of the 17 Mile Mile Drive.
My wife and I took the drive in the morning and the weather was very overcast with coastal clouds. We had a late lunch in Carmel and the sun came out. So, we hopped in the car and headed back to the Lone Cypress to find great late afternoon light.
